WASHINGTON, D.C. - Toledo Democratic Rep. Marcy Kaptur says she supports building the proposed Keystone XL oil pipeline, even though the House of Representatives signed off on the project Wednesday without her vote.

Kaptur skipped Wednesday's vote to approve the controversial 1,200-mile project between Canada and Texas and voted against prior approval measures that Republicans brought before Congress. Her office said she missed the vote because she had a 5:30 p.m. flight to Toledo, and votes weren't called until around 4:40, later than expected.

In an interview before the vote on C-SPAN's Washington Journal, Kaptur revealed that she supports building the Keystone XL pipeline, "but I want the steel in it to be made in the USA."

"I don't want Chinese steel," she continued. "And i want to make sure the trust fund that is set up for liability, if there is a break in a main, that that be paid for by the companies and not the taxpayers of the United States. The bills that have been brought before us to date have not done that. But I'm a supporter of Keystone as well as North American energy independence."

The House of Representatives approved the measure Wednesday by a 270 to 152 vote, with support from all of Ohio's Republicans but none of its Democrats.

President Barack Obama has promised to veto the measure, arguing it circumvents the existing comprehensive pipeline approval process that's examining complex issues including the project's safety and environmental ramifications. The bill didn't obtain enough votes Wednesday to override a veto by Obama.

"It is no surprise the President continues to threaten a veto," said a statement that Holmes County GOP Rep. Bob Gibbs issued after the vote. "With the bill finally going to his desk, I am eager to see if the administration will listen to the American people and a bipartisan majority of Congress or continue to block free-market energy opportunities."
